The HSZ06A106-3X/S245EM00 sandwich plate belongs to the HSZ Sandwich Plates series and is built by Bosch Rexroth for hydraulic automation assemblies. Acting as a direct-operated pressure relief element, it limits system pressure to protect downstream components. The plate is rated for a maximum operating pressure of 315 bar and directs excess fluid along the P–T flow path to return it to tank. The valve is fitted on side E of the stack, matching layouts that group functional elements on that face. A porting pattern conforming to DIN 24340 Form A lets the unit mount on standard subplates without adapters.
The body measures 120 mm in length, 44 mm in width, and 50 mm in height, forming a compact spacer for multi-layer manifolds. It weighs 1.9 kg, so manual handling during assembly remains straightforward. NBR seals are supplied to maintain fluid separation between adjoining plates. There is no locating hole, which means alignment relies solely on the mounting bolts. The external surface carries a Fe/Zn8/Cn/T0 coating to DIN 50979 for corrosion resistance in industrial environments. Because the design requires no external connection points, piping is avoided and flow remains confined within the stacked interface.
